User-oriented, secure, trustful & decentralised social media


Human-as-trust-sensor and reputation mechanism

This deliverable will consist of two phases, starting with the development of user content verification efficacy models (using a range of machine learning algorithms) which extract user activity attributes in real-time (ethically and autonomously in alignment and adherence to approaches defined in D.3). This user modelling phase will then be followed by a second phase (M14) which will integrate the initial Human-as-trust-sensor efficacy models with the EUNOMIA blockchain (D3.4) to extract historic user content verification records (e.g., performance and activity) to generate an ensemble reputation calculation mechanism. The human-as-a-trust-sensor reputation mechanism will then be embedded as an autonomous software module activated via a verification reporting function in the Digital Companion (D4.3).

Trustworthiness scoring

This deliverable has two phases (M14, M28): The first will focus on allowing the fusion of information from the reputation mechanism and confidence scores from the content and context data collection and analysis, enhanced by autonomous data extraction using datamining techniques. The information cascade meta-data relating to trust classification will be integrated in line with pubsub protocol standards for efficient on-demand meta-data from the EUNOMIA blockchain (D3.4). Each component will be an embedded trustworthiness scoring software module in the Digital Companion (D4.4). This component will be designed to draw on both components’ output with a developed objective majority-vote algorithm calculated locally on the Digital Companion. The final version will involve the improvements carriers out following the first phase of pilot evaluations with real users.

Social media content and context data collection and analysis

This deliverable will have two phases: An initial (1st phase; M13) version produced for the first integration prior to pilot phase Alpha, and an updated version (2nd phase; M28) based on the evaluation of this phase. It includes definition of data processing pipeline and development of core processing modules, advancement of core modules and development of a suite of content processing tools, as well as adaptation of tools and packaging of the anonymised data meant for being shared with the scientific community.

Design and implementation of P2P infrastructure

This deliverable includes the design of the P2P infrastructure, the EUNOMIA P2P APIs and a first placeholder implementation of the P2P APIs for the remaining EUNOMIA modules to start integration (1st phase; M13). It will include the implementation of the full P2P functionality (2nd phase; M26).

Design and implementation of security and privacy framework

This deliverable includes the design of security and privacy framework. A first phase for integration purpose with a placeholder implementation of the defined security methods will be made available (1st phase; M13). It will include the implementation of the full security and privacy framework for final release (2nd phase; M26).

APIs and interfaces for decentralised social interaction over the Web

This deliverable is a prototype implementation of the Web-based APIs and interfaces for subscribing/publishing information and supporting federated server-to-server decentralised social interaction, offered as extensions to the opensource software of Mastodon and Diaspora, enabling the integration of EUNOMIA platform with decentralised online social networks.

Digital companion responsive web app

This is the first prototype of the digital companion (due date M14 and a final revision M28), in the form of a responsive web app, built using a cross platform development framework and featuring an adaptive interface so that it can be used in different devices including desktop PCs, tablets and mobile devices. The most appropriate framework for the development of the app will be selected, among the most popular (i.e. react, node.js, Kivi). Using a responsive web app as the materialisation method for the first prototype, it will be easy to invite testers, and perform comprehensive prototype validation, while being able to fully implement all features and functionalities of the digital companion such as user association in social media, trustworthiness scoring and the detection of personal information.

Design and implementation of blockchain infrastructure

This deliverable includes the design of the blockchain infrastructure, the implementation of (1st phase; M13) core blockchain functionality and the revision towards a (2nd phase; M26) full blockchain functionality following pilot phase Alpha.
